The heated watering system seems to work well, but I haven't seen the hens using the nipples yet (it's only been a day since I finished it up). I've removed all other water sources, so I guess they will figure it out - the ducks as well. Regarding the ducks, any advise on how to get them back to the coop. They free range during the day and my 5 y.o. daughter have to wrangle them up at dark. I currently have them with the chickens since it's been very cold (below 0), but have build a separate area for them (aka the quack shack). Once things warm up a bit, I'll transition them to their new area.
Looking forward to learning as much as I can with this new endeavor!
